Andrew,
Thank you for responding to my email and sending me this link. To repeat, here is the problem I sent initially:
Installing Theme from uploaded file: stationpro.zip
Unpacking the package.
Installing the theme.
Theme Installed successfully.
Warning: file(/home/content/s/y/l/sylvaticus/html/wp-content/themes/stationpro/style.css) [function.file]: failed to open stream: No such file or directory in /home/content/s/y/l/sylvaticus/html/wp-includes/theme.php on line 180
Warning: implode() [function.implode]: Invalid arguments passed in /home/content/s/y/l/sylvaticus/html/wp-includes/theme.phpon line 180
I tried redoing it a few times, each time getting the same message. Here was your response via email:
This is common error. If you followed the instructions in the readme.txt file its probably 1 of 2 things either:
The WP uploader sometimes installs the files incorrectly, into a second subfolder.
Check out the files on your server to make sure its like the following: 'wp-content' > 'themes' > 'stationpro' > index.php, page.php, etc...
Incomplete FTP upload, in this case reupload and try again
#1 is the winner, I have a /stationpro/StationPro/ structure now. It seems to work, but I'd rather correct it. Should I move /StationPro up one level and then delete the /stationpro folder, or delete both and try just copying the unzipped folder on my computer?
I should warn you, I'm a total and complete novice here. I understand some things, but not nearly as much as I should. I'm always amazed when I successfully connect using FTP! :-)
Thanks!
Keith

Yes, you should. StationPro is the actual theme and the only file you should need.

People working on Windows are getting this issue, and we're using a different method of compressing files in the future (which we hope prevent this issue! )

do we get notified when someone posts to our questions, or do we just keep checking periodically?

Actually, I'm running Snow Leopard, and my hosted site is on Linux I believe.
The error I pasted came from within WordPress itself. I went to the site admin section and clicked the button to upload the zip file. I navigated through the WordPress dialog box to the zip file I downloaded when I purchased the theme. Again, I'm running Snow Leopard and I use Safari.
I realized that I had uploaded the original zip, and knew that was wrong, so then I went back and uploaded the zip file that was in the unzipped Theme folder, but I got the same error both times. The only difference was the second time, it created that directory structure I mentioned in my initial post.
I will next try using CyberDuck to FTP the StationPro theme to the Theme folder on the hosted server.

(So glad I'm not the only one! :-) --K)
